Stably-locked top cover for railway vehicle

Abstract

A disclosed stably-locked top cover for a railway vehicle comprises a vehicle roof, a skylight and a cover plate, the skylight is installed at the top of the vehicle roof, the cover plate is located above the skylight, grooves are formed in the two sides of the bottom of the cover plate, and inserting plates are hinged to the inner side walls of the grooves. Driving motors and clamping frames matched with the inserting plates are fixedly connected to the two sides of the inner wall of the skylight, the driving motors are located under the clamping frames, output shafts of the driving motors are fixedly connected with gears, and connecting mechanisms are installed between the skylight and the cover plate. Each connecting mechanism comprises two baffles fixed to the skylight and two guide rails fixed to one side of the cover plate. The skylight can be easily opened or closed, the working intensity of crew members is reduced, meanwhile, the inserting plates and the locking mechanism are further arranged, the locking stability of the cover plate and the skylight is improved, the overall structural strength is improved, after the cover plate is opened, noise cannot be generated due to bumpy running of a vehicle, and the using effect is good.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to a top cover with stable locking for railway vehicles. Background technique [0002] With the increasing awareness of human safety and environmental protection, the safety and environmental problems of railway freight transportation have become increasingly prominent. There are many types of railway vehicles in our country. When transporting bulk goods that need to be protected from moisture, moisture or are harmful to the environment, it is necessary to open the top cover in advance to ensure the ventilation inside the carriage. [0003] However, the fully open top covers of existing railway vehicles mostly use cylinders as the power source. During the opening and closing process of the top cover, due to the influence of the change of the center of gravity of the top cover, the movement speed of the piston rod of the cylinder is unstable, so that the top cover is in the ...

Problems solved by technology

[0003] However, the fully open top covers of existing railway vehicles mostly use cylinders as the power source. During the opening and closing process of the top cover, due to the influence of the change of the center of gravity of the top cover, the movement speed of the piston rod of the cylinder is unstable, so that the top cover is in the process of closing. The structure will be damaged by a large impact force. At the same time, the top cover will be accidentally opened after it is closed. The locking strength is not enough, and it will also produce noise when the railway vehicle is running, and the use effect is poor.
